Data on elastic scattering of 96 MeV neutrons from Fe56, Y89, and Pb208 in the angular interval 10−70° are reported. The previously published data on Pb208 have been extended, as a new method has been developed to obtain more information from data, namely to increase the number of angular bins at the most forward angles. A study of the deviation of the zero-degree cross section from Wick's limit has been performed. It was shown that the data on Pb208 are in agreement with Wick's limit while those on the lighter nuclei overshoot the limit significantly. The results are compared with modern optical model predictions, based on phenomenology and microscopic nuclear theory. The data on Fe56, Y89, and Pb208 are in general in good agreement with the model predictions.

A facility for detection of scattered neutrons in the energy interval 50–130MeV, SCANDAL, has recently been installed at the 20–180MeV neutron beam line of the The Svedberg Laboratory, Uppsala. Elastic neutron scattering from C12 and Pb208 has been studied at 96MeV in the 10°–70° interval. The achieved energy resolution, 3.7MeV, is about an order of magnitude better than for any previous experiment above 65MeV incident energy. The present experiment represents the highest neutron energy where the ground state has been resolved from the first excited state in neutron scattering. A novel method for normalization of the absolute scale of the cross section has been used. The estimated normalization uncertainty, 3%, is unprecedented for a neutron-induced differential cross section measurement on a nuclear target. The results are compared with modern optical model predictions based on phenomenology or microscopic nuclear theory.

Photon - gluon fusion analysis of charm photoproduction.

Results on the photoproduction of 10 000 fully reconstructed charmed particles from the 108 recorded triggers of Fermilab experiment E691 have been analyzed in the photon-gluon-fusion model. We find that the total cross section, its rise with energy, and the pT2 and xF distributions can be explained by a high mass for the charm quark (mc=1.74−0.18+0.13 GeV/c2) and a soft-gluon distribution [G(x)∼(1-x)gn, where ng=7.1±2.2].

Experimental Results on Elastic Scattering of Protons on the Light Nuclei H-2, H-3, He-3 and He-4 at 600-MeV

Differential cross sections for the elastic scattering of protons on 2 H, 3 H, 3 He and 4 He have been measured at 600 MeV. Proton-deuterium elastic scattering is investigated in a four-momentum transfer square t -range corresponding to Coulomb-nuclear interference in order to determine the nucleon-nucleon amplitudes at 600 MeV. For the other nuclei, we investigate the t -range corresponding to the first and second maximum, in order to determine the mechanism of the nuclear process. A few physical comments on the results are made.
